Leaders in Living Rooms LILR 150 | Warren Bird and Jim Tomberlin on Why Multisite is Back and Booming
As the church enters a new season of ministry in 2026, this episode of Leaders in Living Rooms invites leaders to re-examine what they think they know about multisite ministry. Sean Morgan is joined by Warren Bird and Jim Tomberlin to explore how the multisite movement has quietly shifted from simple replication into a multiplying, movement-driven model focused on discipleship, innovation, and the Great Commission. Together, they unpack common critiques of multisite churches, highlight emerging “pacesetter” churches shaping the future, and preview an ambitious national research project designed to equip churches navigating growth, complexity, and mission at scale.
Welcome to Episode 150 of the Leaders in Living Rooms Podcast with Sean Morgan.
